On the hunt for mushrooms and black walnuts

For anyone reading out there, can someone tell me where I can get organic mushrooms - for cooking - in Connecticut, or at least somewhere in the area? I know I can get them from the grocery store, but would like to find them locally and not wrapped in cellophane and styrofoam.

Also, I know black walnuts are more of a Southern find, but are there any farms that would be willing to ship them?

Leave comments, please!
